Hi Alex and Georg,

Very interesting project. I hope the Axiom guys know how lucky they are to get you both into the project.
And I'm just in time to grab a nice T-shirt.

I wish you all good luck and trust you get the best out of this more competitive camera.

I set preview to AUTO for recording. You can frame shots with x5 in low res and set focus with x10 then just 'imagine' the rest of the frame when recording with the grayscale, realtime 5x preview.

Hi Andy,

Can you share your ML config file? I'll add a config with ML50D_ANDY_STYLE
I'm struggling with the 50d. I can't get it to work in a convenient way.

Thanks

Hi I picked up 50D testing again.

I have one problem. focus, *, halfshutter and set start RAW or MLV record
How to set it on just one button so I can use set or AFon for ETTR and AF

Thanks

Wow those are very high quality, natural and pleasing looking results. Well done!

Hi Africashot,

Very nice work. It looks like a good formula with the local company and footage you can collect in a day. Video shots are nice, image quality is good enough.
I've shot a promo of a camp in the Masai Mara back in 2011. It's really nice to do and I hope to do lots more.  Let's hope others won't take all the fish out of the pool, but that's life.  Good luck with further projects. If everything goes as planned I'll return to Masai Mara this summer for a 3 week shoot.

Hmm didn't know what that crop mode did till today lol. Makes getting macro shots super easy.

It also gives you a whole lot larger depth of field (DOF) at the same field of view (magnification of the subject). Distance to the subject matters for DOF. And you sort of override the closes focus distance by magnifying the image. A 50mm with closest focus at 0.35m can be used for macro work. You suddenly have a 150mm at 0.35m. Try to find a non-macrolens at 150mm that can focus this close. And finally you can choose to make the working distance bigger which is nice for alive insects.

config startup presets

I was thinking of sharing preset files for certain tasks.
Like one just for raw/mlv video and strip everything else from the menu. Just a few relevant items. It's great for newcomers. And another preset for timelapses.

I'm suprised more people don't record 5x there, I guess no display filter

I think that is because of the total cropfactor of 4x. I have a tamron 11-18 and on the canon it is great because in a forest you can capture an image that looks like a forest. The cropfactor makes it a 44mm and trees don't fit in there any more. Walking backwards could work and with a decent centre resolution and with little distortion the image looks great. Very detailed 1080p. If that doesn't work i'll go for a dualiso timelapse on the old fashion shutter.
I don't choose between RAW and H264. I just pick the one that fits the situation best. And sometimes I shoot with both the see what works best in post.  My lenses are adapted to canon ef and fit on both cameras. Except for my tamron on the GH2. It lacks control over both aperture and AF. I want to switch that one for a nikon version and use a Nikon G to Canon EF adapter to gain manual control over aperture. Hope that works.

Will make time for a test for sure...

Here is a color corrected image from the VAF filter test with the Promaster UV filter in place using Capture 1 trail version to export flat 16-bit Tiff image and then applied Color Correction in AE with Synthetic Aperture to create this look... (Take notice to the detail and the lack of moire! Obviously the color is jumping out in a great way, right?)

Strange dimensions. What was the resolution of the original png? Maybe you can share one PNG frame?

For me the 50D is a specialist tool. I shoot mostly wildlife and landscapes and my GH2 will remain my main camera for most of the shots. The GH2 can handle most situations very well. The 50D comes in at very strong backlight situations. Like straight or near straight into the sun at sunset situations where preserving some extra shadow detail and subtle tones is preferred over total clipped shadows.
I think ML RAW has a couple more stops headroom over GH2 if you follow the ETTR hints and expose just before the histogram shows "over". I compared that to the ML h264 histogram and the RAW ETTR pushes the exposure way beyond the point I would choose in h264 mode. In post (Adobe RAW converter) there are a lot of options to recover what's needed. RAW dual iso video would be nice but RAW and some noise filter are pretty great too.
So for now I grab my 50D only at strong contrast situations in 1080p cropmode, for instance when skies offer interesting cloud formations to preserve. The 1x mode is nice for 720p.

The MLV/RAW player is a very nice tool for sorting out shots.
It's not perfect but let's you find which shot is which.

Hi,

I've spent a lot of time reading into the 50d and this is what is know so far that might help you.
RAW options for 50d are limited and most of them can already be achieved with a Komputerbay 64GB 1000x.

RAW limitations for 50d

FPS
The camera offers only 1080@30p which means framerate can NOT go faster than 29,97fps. Even with a 150000x CF

RESOLUTION
- normal shooting mode 1584x1058. This is an absolute limit and horizontally roughly 1/3rd of the photo resolution
- cropmode: uses the center of the sensor and is limited to 2000x1080

One very important setting is: [Global draw off while recording]
This is found in the RAW video submenu and the "off" setting makes it work

This setting disables all overlay functions at once (zebra, peaking, histogram etc)  to put all resources  to writing proper frames to the CF card.

So most RAW functionality is already possible except for framerates between 23.976 and 29,97.

I would advice to accept these limitations and make the best of them. Andy600 clearly showed a while back in this topic that you can shoot gorgeous footage with this camera at both 1584x and 1920x resolutions.

So good luck

Very nice work! Easy quick review now saves so much time

Hi Andy,

I knew about the photomode. And of course the latest build is the latest build. I'll just stick to exploring the latest build properly, before asking any more questions.

I can't find an answer for the following question:

What is the status on dual_iso video on 50d?

My primary use of the 50d is crop raw video in situations with a strong backlight. I love those shots and dual iso can push the limits even more. Otherwise dualiso in timelapse is great too, but can't handle moving subjects like video.

Good to see the warning is working... it can be falsely triggered if you select not exact FPS and 22 FPS, have to fix that.

Well they are gone with these setting: They work fine

- Camera on M mode with all Fn functions disabled
- Only one module enabled: raw_rec

ML enabled functions
- Exposure override
- Shortcuts iso/kel, av/tv
- Global draw on: but off while recording (in RAW submenu set to "off" to work)
- zebras, histogram with ETTR hints for best exposure choice

- movie record 1920x1080
- REC key: half shutter
--FPS override 23,976
- RAW video on 1920x1080

- Dialog timers: disabled

Now I can do 1920x1080@24p(23.976) in cropzoom at around 80-81MB/s on a Komputerbay 64GB 1000x

Hope this helps other to get is working.
From these settings you can try other stuff. This just works.

Oh one thing. Which shutter should I believe: The one in ML liveview that increased in very small increments or the shutter speed on the top LCD that progresses much faster?
When the liveview shutterspeed is at 1/100 the top lcd is 1/500.

[EDIT]found answer through ADTG search: it's the liveview shutter. The top one is for photomode (1%)

There is no manual movie mode in reality, you need expo override. None of the controls really apply to LV, only photos.

ok Thanks, i'll try that

author=Andy600 BTW @bart - Why 21fps?

over 22fps I get these heating warnings. I did get some 1080p24 footage but dropped back to 21fps. I first need to figure out the basics and go from there. My first cropzoom landscape at 11mm looked pretty great.

I want to use 1080p crop just for extreme contrast situations (pitty about the dualiso in video, but it's great in plain raw too)

Then I want to do some tiny cropzoom macroshots with rackfocus and digital dolly. Maybe rack from one tiny mushroom to another all raw with strong backlight where they get transparent.
I'll post some samples as soon as I've got the basics right.

I am in M mode and used the "clear all Custom Func" an delete magic.cfg.
just at clean startup and no modification I press 'func' for ISO and it goes from 100 160 eq100 and stays on eq100

I need some help.

What I want is everything off except for mlv module and digic zebras highlights, histogram with ETTR hints, shortcuts ISO,tv,av
With these settings I want to do 1920x1080 crop at 21fps.

problem.
I can't set exposure. shutter and iso change very little in liveview while the canon top lcd changes iso/shutter in predictable steps. I don't see any change in liveview and can't compensate for ETTR hints. Aperture seems to change the number displayed in liveview but I don't see any change in picture brightness or ETTR hints.

What is wrong? I got the Fn functions all to 0 and the display still reports 'ALO NEUTRAL', I can't set exposure simulation 'ON'

Hi, I switched my 550d for a 50d with KBay 1000x 64GB

First test today with 20sept bugfix build. So much has changed last few months.

I just tried cropzoom 1920x1080 21-23.976 fps
At one point I had a pretty long run 23.976 1080p at 80.6 MB/s
But later on it couldn't continue so I dropped to 21fps

loaded only: MLV, ETTR, Dual iso (set to 100/800)

comments:
- nice new fonts
- MLV and ETTR modules and liveview AF conflict on 50D. I can't run ETTR on set and use halfshutter to start video. With ETTR to set, it also starts on half shutter. I also loose AF in liveview because of the halfshutter. Both half shutter and * start video and both halfshutter and set start ETTR.
- My tamron 11-18 seems accurate framed in hacked cropmode, the 5x zoom display from canon was off when pressing INFO.

The 1080p output is by far the best i've had from canon footage. Great work guys!

nice, i'll check that out

I am talking about just overlay functions as a fieldmonitor. No external controlling of the camera. The overlays are already very valuable on camera's that have decent video features but lack these overlays.

And I bet it's a lot of work. It's just an idea.

Very nice and responsive site, congratulations!
I think it's a well thought through setup and design that fits the current state of the project.
The amount of information on the frontpage is limited, but good to maintain in this very dynamic development environment. Maintaining manual and wiki will still be tough.

Good luck to you all! You have made so much wonderful progress. I miss being part of that.
